VATEReCLOSET-FLUSHING MECHANISM.

Application filed November 19, 1913.

To all whom it may concern:

Be it known that I, SAMUEL J. STEVENS, a citizen of the United States ofAmerica, and a resident of the city of St. Louis and State of Missouri,have invented a certain new and useful Improvement in Water-Closet-Flushing Mechanisms, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,forming a part of this specification.

My invention relates to mechanisms for flushing water closets and, moreparticularly stated, the invention pertains to means associated with avalve of a flushing mech anism, and means with which said valve iscooperable, whereby the valve is automatically held from return to aclosed position when it is unseated until the flushing tank is emptied,and whereby the valve is caused to automatically return to its seatimmediately following the emptying of the tank.

Figure I is a vertical section through my valve mechanism, with the tankcontaining the mechanism shown partly in elevation and partly brokenaway and in section. Fig. H is an enlarged vertical section of the lowerportions of the valvemechanism. Fig. III is an enlarged vertical sectionof the support and bushing for the valve stem, showing the stem ininclined and supported position.

In the drawings: A designates a flushing apparatus tank, in which isarranged an outlet connection B, which receives the attachment of aconducting pipe leading to a water closet. The connection B is providedat its upper end, within the tank A, with a valve seat member 0, and hasattached to it a vertical overflow pipe I). The overflow pipe serves asa support for the valve op-- erating lever E, to which a valve liftingrod F is connected.

No invention per se is herein claimed for the parts thus far described,and they may be of any ordinary or preferred construction.

1 designates a support within the connection B, beneath the valve seatmember C, this support being provided with a vertical opening located atthe diametric center of the connection B. In the opening just mentionedI preferably arrange a bushing 2, which has screw thread engagement withthe support 1, which is adjustable in and re- Specification of LettersPatent.

movable from said support, as will hereinafter more fully appear.

3 designates a valve, adapted to seat upon the valve seat member G ofthe outlet connection, to close said connection, as seen in Fig. II. Thevalve is provided with a top stem 4, to which the lift rod F is looselyfitted.

F designates a float connected to the valve stem 4 by a rod 6. The valve3 is also provided with a lower stem 7, which is operable inthe support1, and is provided with a detent notch 8, the said notch being locateddiametrically opposite the float 5 con nected to the upper valve stem4%.

In the practical use of my flushing mechanism, the operation is asfollows: When the valve 3 is lifted from its seat to open theentranceway into the outlet connection 13, the lower stem 7 is movedupwardly in the support 1, until the detent notch 8 becomes locatedabove the top of said support; or where the bushing 2 is used, above thetop of said bushing. The float 5, by its tendency to rise in the tank A,acts to tilt the valve and its stem into the position illustrated inFig. I; and, as a result, the detent in the notch 8 in the lower valvestem immediately engages or settles upon the support or the bushingtherein, if the bushing is employed, whereby said support is caused tosustain the valve in its elevated position, pending the emptying of thetank. Upon the escaping water reaching the level of the float 5'andpassing thercbeneath, the float is permitted to descend; and, in itsdownward movement, acts to return the valve and the lower stem 7 to anupright position, so that the detent of the lower valve stem isdisengaged from the support 1 or its bushing, after. which the valvereadily resumes its normal position upon the valve seat 0 of the outletconnection, through which the water in the tank A has escaped.

It will be understood from the foregoing that the valve 3 isautomatically adjusted into position to be upheld from its seat, due tothe rise of the float 5 in the water in the tank A, when the valve isfirst lifted; and that the return of the valve to its normal position isautomatically accomplished by the falling of said float, due to theescape of the water from the tank.

I preferably utilize the bushing 2 in the support 1, in order that thebushing may receive the wear of the valve stem t, which would otherwisebe imposed upon said support, the bushing may be readily re placed by anew one from time to time, when necessary, withoutdisturbing theconnection B, or the support 1 carried thereby.

The bushing being adjustable, its position in the support 1 may bereadily altered, so that'it will sustain the valve 3 at any desiredelevation relative to the valve seat member C.

I claim l.- The combination with the valve seat of a flush tank outlet,of a su portbelow said valve seat, a tiltabl'e valve movable to and fromsaid Valve seat, a stem carried by said valve adapted to engage saidsupport to hold the valve away from said seat when the valve is tilted,and a float by which said valve is tilted to place said stem inengagement with said support.

2. The combination with the valve seat at a flush tank outlet, 'of asupport below said valve seat, a tilt'able valve movable to and fromsaid valve seat, a stem carried by said valve slidably fitted to saidsupport and having a detent for engagement with said support, and afloat :t'or tilting said valve to cause the detent of said stem toengage said support when the valve is elevated from said seat.

The combination with the valve seat of a flush tank out1et, of a supportadjacent said valve seat, a tiltable valve movable to and fromfsaidvalve seat, a detent stem oarried by said valve, and a float rigidlysecured to said valve adapted to tilt it to place said detent inengagement with said support when the valve is elevated from said valveseat, said float being located at one; side of the axis of the valve forthe purpose set forth. t

4, The combination with the valve seat of i a flushtanlr outlet, of asupport adjacent to 1* said valve seat, a bushing removably'mount- 2 edin said support, a tiltable valve having -'a v1 detent stem operable insaid bushing adapted to engage the bushing to hold the valve away fromits seat when'elevated and tilted,

the valve is tilted when elevated from sai seat.

a flush tank outlet, of a support adjacent to said valve seat, a bushingadjustable in said support, a tiltable valve having a detent stemoperable in said bushing adapted to engage the bushing to hold the valveaway from its seat when elevated and tilted, and

a float carried by said valve by which the valve is tilted when elevatedfrom its seat.

'6. The combination with the valve seat of a flush tank outlet, of avalve movable toward and away from said seat, afloat located one side ofthe axis of the valve and and a lower detent stem, both of said stemsbeing rigidly secured to said valve,a float rod rigidly secured to saidupper float stem and extending therefrom at an angle to the axis of thevalve, a float secured to said float rod so as to tilt the valve whenthe latter rises adapted to engage said detent stem so as to supportsaid valve and float when the valve occupies its tilted position. 1

8. The combination with the valve seat of a flush't'ank outlet of avalve movable toward and away from said valve seat,a stem extending fromsaid valve, a float rigidly secured to said valve, the said float beinglocated at one side of the axis of the valve, and the said stem beingprovided with a detent "shoulder at the opposite side of the axis ofsaid valve, and'asupport, the float being operable to tilt the valve soas to engage said detent shoulder with said support when the -lattermoves from its seat;
